10.6 Client List Screen
The DHCP table shows current DHCP client information (including IP Address,
Host Name and MAC Address) of network clients using the NBG-417N's DHCP
servers.
Configure this screen to always assign an IP address to a MAC address (and host
name). Click Network > DHCP Server > Client List.
Note: You can also view a read-only client list by clicking the DHCP Table (Details...)
hyperlink in the Status screen.

DESCRIPTION
Select From ISP if your ISP dynamically assigns DNS server
information (and the NBG-417N's WAN IP address). The field to the
right displays the (read-only) DNS server IP address that the ISP
assigns.
Select User-Defined if you have the IP address of a DNS server.
Enter the DNS server's IP address in the field to the right. If you chose
User-Defined, but leave the IP address set to 0.0.0.0, User-Defined
changes to None after you click Apply. If you set a second choice to
User-Defined, and enter the same IP address, the second User-
Defined changes to None after you click Apply.
Select DNS Relay to have the NBG-417N act as a DNS proxy. The
NBG-417N's LAN IP address displays in the field to the right (read-
only). The NBG-417N tells the DHCP clients on the LAN that the NBG-
417N itself is the DNS server. When a computer on the LAN sends a
DNS query to the NBG-417N, the NBG-417N forwards the query to the
NBG-417N's system DNS server (configured in the WAN > Internet
Connection screen) and relays the response back to the computer.
You can only select DNS Relay for one of the three servers; if you
select DNS Relay for a second or third DNS server, that choice
changes to None after you click Apply.
Select None if you do not want to configure DNS servers. If you do
not configure a DNS server, you must know the IP address of a
computer in order to access it.
Click Apply to save your changes back to the NBG-417N.
Click Reset to begin configuring this screen afresh.
